She taped up Macavity - The Mystery Cat by T.S. Eliot, which she picked because she thought it would appeal to the cat.
There's also The Contents of My Desk by Kenn Nesbitt (a good "school" poem).
The third poem she put up was Rhapsody, which is one of those poems that I would memorize, if I memorized poems:
by William Stanley Braithwaite (1878-1962)
I am glad daylong for the gift of song,
For time and change and sorrow;
For the sunset wings and the world-end things
Which hang on the edge of to-morrow.
I am glad for my heart whose gates apart
Are the entrance-place of wonders,
Where dreams come in from the rush and din
Like sheep from the rains and thunders.
In addition to the printed poems, there's also a cinquain of hers, from when she was teaching the cat about cinquains:
pointy gray objects
fall in...you're doomed!
So really, that was safety warning for the cat, as well as a poetry lesson.
